Wd40 has stained indian sandstone - Hoping to find a remedy

[AB10]

I have managed unfortunately to spray WD40 on areas of Indian sandstone which has resulted in bad, noticeably dark staining on the sprayed areas. (I had a plastic sheet down but the spray travelled further than I expected). I have tried soap liquid, Jeyes fluid, pressure washing, scrubbing and elbow grease! - but nothing has worked. I have not tried acid cleaner because of the danger of even worse staining - should I try it? Is there anything else I could try?

Do you have a picture that you could post. I dont have much experienece of WD40 being spilt on stone, but Roger who is the Brew Cabins resident expert on all things stone cleaning will know what to do. He will be along shortly

Apply a degreaser wait a few hours then wash off.

I had oil from food on my Indian sandstone and I also used the same product on my block paving when I had engine oil and brake fluid on it....

It was recommended by roger R&A on here...

Great advice from roger as worked a treat... But please wait and see what he says as he may suggest something else...

Also if you do try anything to clean it test it on a spare slab or in a small corner..

Thank you all for the replies - I will try all ideas and let you know. And I look forward to hearing from Roger! Photo as suggested by London Stone Paving is below (I hope). I think you can see the square light area in the foreground where the plastic sheet was - surrounded by areas of WD40 staining.

I wouldnt try anything until the oracle (Roger) has spoken. Stone is a natural material and can react badly to chemicals. The wrong move at this point could make things a lot worse. I'll send Roger a PM and see if I can raise him

Cheers Steve just got your pm,

Ann that is a fair bit of staining there, give me 24 hours as the product Rimexboy used will do this but will cost you a bit as it looks a large area from the photo, and there is another product that should do this, but just let me check how it works on Sandstone.

The worst thing you have here is it has dried in with the hot weather we have had, how long has the WD been on the surface for?
I do know someone up your way that can fix this for you which might be a better option to go for, plus what is the "orange" stain going towards the table?


TheRockConcreting, WD40 is a degreaser so putting another on top of the WD, wouldn't be a way I'd go personally.

Roger, thanks for your reply. The WD40 was sprayed yesterday morning, and the area was hosed down, with and without soap liquid, yesterday evening.

The orange staining was another disaster - not entirely of our making! It's rust from supposedly maintenance free garden chairs - it started off as small patches but weather and hosing seem to have spread them somewhat. Added to the red roof sealant spots we have all over an area you can't see on the photo, which were caused by roofers next door working on a windy day, our 3 years old patio makeover is looking rather sad - though we still enjoy it! Would be good to sort out the problems though, one way or another.

I was on the understanding WD40 is a fish oil and using a degreaser that breaks down the fish oil proteins would have worked?

Don't know about the fish oil? it is a petroleum based product, de-greaser & lubricator I'll send you the MSDS if you want.

Ann,

Did a check for you today, and it is like I thought a poultice is going to be the way forward, problem here is it will get expensive, depending on the size of paving that has the WD40 on it. I was hoping that one of my suppliers would have a product that would get this out for you, WD40 is a light oily substance and regular degreaser's are great for engine oil etc which are heavier but won't catch the lighter ones.
2 ways you can approach this you could try the product Rimexboy used the Extra KT and try it yourself, or I can put you in touch with someone in your area that does this sort of clean, and could look at the Rust stains etc as well if you wanted?
Sorry there isn't a cheaper option, just let me know if I can help you further.

we use water dispersant 40 on blue engineering bricks to clean them and make them shine
this shine doesnt last for ever
i guess the oils evaporate after a time
option 3 is to leave it and let the good old british weather do its best

Problem is Tony, the stain or shadow will remain on the Sandstone, spraying brick to clean them to make them shine is one thing to have an accident and not wanting the results is another

[lutonlagerlout]

I totally agree roger , but time and time again we see this with spray on fence treatments,weedkillers, wine,blood you name it

the reality is IMHO that the cost of cleaning specific stains may outweigh the cost of replacing the affected stone

I dont know what this specific stain would cost to put right but surely given sun wind rain and ice it will disperse itself given time?
